NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyMatch the items in column I with the items in column II.
| Column I | Column II |
| a. N2 (g) + O2 (g) → 2 NO (g) | i. Disproportionation redox reaction |
| b. 2Pb(NO3)2(s) → 2PbO(s) + 4 NO2 (g) + O2 (g) | ii. Decomposition redox reaction |
| c. NaH(s) + H2O(l) → NaOH(aq) + H2 (g) | iii. Combination redox reactions |
| d. 2NO2(g) + 2OH–(aq) → NO2–(aq) + NO3– (aq) + H2O(l) | iv. Displacement redox reaction |
1. a = iii; b = ii; c = iv; d = i
2. a = iii; b = iv; c = i; d = ii
3. a = ii; b = iii; c = iv; d = i
4. a = iv; b = i; c = iii; d = ii
